500 Exception! SmartConsole R80.10

Hi, do you know the main reason for this exception? It seems that is something about Java and not the checkpoints but I'm not sure.

Just for reference.

It says:

500 Exception! An error ocurred while updating the entries. See the inner exception for details: The INSERT statement conflicted with the FOREIGN KEY constrant: "FK_Tra_Gestion_Tra_Contactos". The conflict ocurred in database: **********. The statement has been terminated."]"Property": "Requested failed"}]
